I use LookOut and have tested the lost phone function which works pretty well. I need to upgrade my version of CM as soon as I have the time. Before I do I'll try to remotely wipe my device and report back.

I'm using Prey myself. I'd just look at each one of them, check their features and see if they meet your needs.

What phone do you have? Some manufacturers (eg HTC and Samsung) make their own tracking apps that they embed in their newer phones. I have a Galaxy S and have Samsung Dive set up for mobile tracking.

I have a Galaxy S too, The AT&T Captivate. What's the Samsung Dive?

@Adam samsungdive.com integrates with the Mobile Tracker section under Location and Security in the phone's settings. Unfortunately I don't think that it's available on all of the US Galaxy S variants for some reason. According to this it should be coming to US AT&T Captivates "soon" theandroidsoul.com/2010/07/02/…
